What are RAM Heat Spreaders?

For those heavy memory users out there, especially those of you that routinely ‘overclock’ your RAM, a heat spreader is an easily installed protector that fits around the outside of your memory module that actively disperses the extra heat generated by overworking your hardware.

Similar in size to the memory modules themselves, they are installed around the outside of your RAM stick and stuck in place with adhesive. Dispersing this heat means that your memory hardware is less likely to encounter malfunctions that can happen due to raised temperatures.

What is a Memory Rank?

To a relative computer layman, the term Memory rank is a fairly innocuous one. To someone well versed in the inner mechanics of a PC, then it is an integral hardware component that allows more space to be allocated for your computer’s data. In this short article, we will try and explain just a little bit about memory ranks for those of us who don’t find this kind of thing easy to understand.

The Definition

A Memory Rank is a multiple of DRAM chips, organised in lines (or ranks), that are connected to same microchip.

The term ‘Rank’ was coined by the standards authority for the memory industry, the Joint Electron Device Engineering Council (or JEDEC for short), as a way to differentiate between the separate memory banks that exist on a module. ‘What is a module?’ I hear you cry. Well, simply put, it is general term for a number of separate electronic circuits grouped together on a circuit board to perform basic operations within a PC’s internal workings.

A Memory Storage Area

To further break it down into its base parts, a memory Rank is an area of data that uses some, or all in some cases, of a module’s internal memory chips. 1 Rank is equal to 1 data block that is 64 bits wide. A module can be made up of 1, 2 or 4 ranks of data and is referred to as being single, dual or quad rank.

Single or Dual Sided

In addition to having up to 4 ranks of data blocks, a memory module can also be dual sided i.e. it has a bank of chips on both sides of the PCB, it will be denoted as being dual sided.

What to look out for - When looking through technical PC manuals which describe and explain the inner components of a computer in detail, it is easy to get intimidated by the often confusing terminology. With regards to memory, denotations are the thing to look out for. For example, a single sided, dual rank module will be annotated as 1Rx2 or a dual sided quad rank module would be 2Rx4.

Pros and Cons of Higher Rank Modules

Of course, having more ram can’t typically be seen as a bad thing, but it can lead to problems installation, depending on your server. Servers will sometimes have a limit on the amount of ranks it can house.

If you’re not sure on your servers limitations, you should refer to your manual for specifics and remember to keep an eye out for the annotations mentioned above. Alternatively give our technical suppport team a call or email and they will confirm the exact specification that will work within your current server setup.

Conclusion

We hope that we have made the complicated world of circuit boards, memory slots and ranks that little bit clearer for you. With a little guidance, understanding what your PC needs to work effectively doesn’t need to be a traumatic experience.
